HEAD FOR ROTARY PUMPS.

SPECIFICATION forming part of Letters Patent No. 650,985, dated June 5, 1900.

Application filed June 3,1899. Serial No. 719,288. (No model.)

To to whom it may concern.-

Be it known that 1, ROBERT J. NORTHAM, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Heads for Rotary Pumps, of which the following is a full, clear, and exact description,= reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improved head and bearing intended more especially for rotary pumps and which may be applied generally to a device in which a vertical shaft is rotated; and my invention consists in certain features of novelty hereinafter described and claimed.

Figure I is a side elevation of my improved head, showing a portion of the well-casing broken away. Fig. II is a'vertical section of the upper bearing, taken on line II II, Fig. I. Fig. III is a vertical section of the lower hearing, taken on line III III, Fig. I.

Referring to the drawings, 1 represents a rectangular frame in which the bearings of my improved pump-head are placed. The frame 1 is preferably made in sections 2 3, the upper section 2 being bolted at 4. 5 to the lower section. By forming the frame 1 in sections access may be had to the bearings and the parts more readily placed in position.

6 represents a vertical pump shaft or rod having upper and lower bearings in the rectangular frame 1.

7 represents an operating-shaft having a pulley 8 thereon, through which power may be applied, the inner end of said operatingshaft coming within close proximity and terminating at the line of the vertical shaft 6.

9 represents a two-part boxing .on the respective sections of the frame 1, said boxing receiving the shaft 7.

10 represents a beveled gearsecured to the vertical shaft 6, and 11 represents a beveled gear secured to the driving-shaft 7 said beveled gears meshing with each other. Said beveled gears are preferably located within the frame 1 and between the upper and lower bearings of the shaft 6, the strain being thus equally distributed between said bearings.

I do not confine myself to beveled gears in the operation of my pump, as other forms of gears maybe usedfor instance, miter-gears, 85c. Neither do I desire to confine myself to the open frame 1, as the gears may be boxed in, if found desirable.

12 represents a collar on the shaft 6, and 13 a set'screw, whereby the collar may be adjusted' on said shaft.

14 represents asleeve surrounding the shaft 6 and resting upon the collar 12, the shaft being free to rotate within said sleeve.

15 represents a cup surrounding the upper end 14 of the sleeve 14, which is provided with an annular groove 16.

17 represents a lower bearing-plate placed within the groove 16, on which ball-bearings 18 rest, and 19 represents an upper bearingplate resting upon the balls 18.

20 represents an annular ring forming an outer bearing for the ball-bearings, said ring resting in the groove 16. The upper end of the sleeve forms the inner bearing for the ballbearings.

21 represents a coil-spring surrounding the shaft 6, having its lower end resting on the plate 19, and 22 represents jam-nuts secured on the shaft 6 above the coil-spring, said coilspring serving as an adjustable bearing for the downward thrust of the pump-shaft 6.

23represents a well-casing having its upper end secured at 24 to a ring. 25 of a boxing 25.

26 represents a chamber in the boxing through which the water passing from the easing flows.

.27 represents an outlet or discharge pipe leading from the boxing 25, and 28 a peep-hole or'plate by which access may be had to the inside of the boxing.

29 represents an annular plate secured to the upper end of the boxing 25 and having a pendent sleeve 30 extending downwardlyinto the chamber 26.

34 represents a lower bearing-plate and 35 an upper bearing-plate, with ball-bearings 36 between said plates.

37 represents an annular bearing ring placed inside of the flange 32, forming an outer ball-bearing, while the upper end of the sleeve 30 forms the inner ball-bearing. The beveled gear 10 rests upon the plate 35.

38 represents the blades 011 the shaft 6 for raising the water.

39 represents bolts for securing the plate 2.) and boxing 25.

I claim as my invention A head for rotary pumps comprising a reotangular frame having a horizontal bearingbox, and an annular plate at the bottom of the frame formed with a pendent sleeve having its upper end projecting above the annular plate and with an annular flange surrounding the projecting end and providing an annular pocket, the boxing secured to and beneath the an n ular plate, the lower bearin gplate and annular bearing-ring located in the annular pocket, the lower series of balls, the upper bearing-plate located on the lower series of balls, the Vertical shaft, the bevel pinion keyed to the vertical shaft whereby the latter is adjustably supported on the upper bearing-plate, the horizontal shaft, the bevel gearwheel secured to the horizontal shaft and meshing with the bevel-pinion,the cup formed with a pendent sleeve, having its upper end projecting into the cup, the lower bearingplate and annular bearing-ring located in the cup, the upper series of balls, the upper bearing-plate located on the upper series of balls, and the spring and nuts whereby the vertical shaftis supported on the upper bearing; substantially as described.

ROBERT J. NORTHAM.
